The PL-259 had a huge jump in impedance.  How much of an effect does that jump in impedance have on receive signals?  Now, we did this about 1974 or so, so the quality of materials and frequency responses may have changed since then.  How many of these connectors needs to be installed before a noticeable change in a week DX signal is detected?   Do you count the Male and Female connector as one or two points of  loss?

The impedance bump is less than an inch long. If the ring is really
tight, the impedance bump doesn't introduce loss so much as it
introduces a change of impedance seen through the connector. At HF you
probably can't measure that change without introducing 50 connector
pairs one after the other.
